本篇文章和大家了解一下使用javascript實現前端分頁效果的方法。有一定的參考價值,有需要的朋友可以參考一下,希望對大家有所幫助。
需求:實現分頁請求表格數據,ajax暫時沒寫,只寫了分頁的功能。
效果圖:
當頁數是第一頁的時候,首頁和向前那個按鈕處于禁止點擊的狀態
各個按鈕都正常的狀態
當頁數是第一頁的時候,首頁和向前那個按鈕處于禁止點擊的狀態
各部分的代碼如下:
html部分:
<!-- 分頁 --> <div class="pageBox"> <div class="pageTotal">共<span id="dataLength">88</span>條</div> <div class="pageContent"> <button class='firstPage'>首頁</button> <button class="prevPage"></button> <button class="showPage"></button> <button class="nextPage"></button> <button class="lastPage">尾頁</button> </div> <div class="selectSize"> <div><span class="numSelect">10</span> <span>條/頁</span></div> <div class="icona"></div> </div> <!-- <div id="test1" ></div> --> <div class="goPage"><span>跳至</span><input type="text" id="goPageInp"><span>頁</span></div> <ul class="pageSelectShow"> <li data-num="10">10條/頁</li> <li data-num="20">20條/頁</li> <li data-num="50">50條/頁</li> <li data-num="100">100條/頁</li> </ul> </div>
CSS部分:
* { padding: 0; margin: 0; } body, html { width: 100%; height: 100%; } .pageBox{ width: 60%; margin-left: 20%; margin-top: 200px; position: relative; height: 50px; } .pageBox>div{ float: left; margin: 0 10px; } .pageContent>button{ float: left; margin: 0px 4px; border: none; outline: none; } .goPage,.pageTotal{ height: 30px; vertical-align: middle; font-size: 14px; } .goPage{ right: 50px; } .goPage span{ display: inline-block; color: #999999; } .goPage input{ display: inline-block; width: 50px; height: 30px; margin: 0px 5px; border: none; border: 1px solid #ccc; border-radius: 4px; text-align: center; } .pageTotal{ left: 50px; line-height: 30px; font-size: 15px; color: #999; } .pageTotal span{ margin: 0 3px; color: #333; } .selectSize{ width: 100px; height: 30px; border: 1px solid #ccc; border-radius: 4px; font-size: 14px; text-align: center; line-height: 30px; vertical-align: middle; position: relative; } .selectSize>div{ float: left; margin-left: 5px; } .icona{ width: 20px; height: 20px; background-image: url('./down.png'); background-size: 100% 100%; background-position: center center; margin-top: 5px; cursor: pointer; position: absolute; right: 6px; } .pageSelectShow{ width: 100px; height: 162px; border: 1px solid #ccc; overflow-y: auto; position: absolute; top: -170px; left: 400px; list-style: none; font-size: 15px; display: none; background: #fff; border-radius: 3px; } .pageSelectShow li{ width: 100%; height: 40px; line-height: 40px; text-align: center; cursor: pointer; } .pageContent>div{ cursor: pointer; height: 30px; } .firstPage,.lastPage{ width: 60px; } .firstPage,.lastPage,.showPage{ background:rgb(67, 133, 255); color: #fff; font-size: 15px; line-height: 30px; text-align: center; border-radius: 4px; } .showPage{ width: 40px; } .prevPage,.nextPage{ height: 30px; width: 50px; border: 1px solid #ccc; border-radius: 4px; background-repeat: no-repeat; background-position: center center; background-size: 20px 20px; } .prevPage{ background-image: url('./prev.png'); } .nextPage{ background-image: url('./next.png'); } .nowtouch{ color:#009E94 }
JS代碼:
//點擊顯示選擇條數的div var showFlag = true; var numcount = 1;//默認第一頁 var dataLength =10000; $('#dataLength').text(dataLength); var allCount = Math.ceil(dataLength / 10); console.log(allCount); //分頁跳轉 $('.showPage').text(numcount) if (numcount === 1) { firstDis(true, 'not-allowed', '0.5') } if (numcount === allCount) { lastDis(true, 'not-allowed', '0.5') } $('.icona').click(function () { if (showFlag) { $('.pageSelectShow').css({ 'display': 'block' }); $('.icona').css({ 'background-image': 'url(' + './up.png' + ')' }) showFlag = !showFlag; } else { $('.pageSelectShow').css({ 'display': 'none' }) $('.icona').css({ 'background-image': 'url(' + './down.png' + ')' }) showFlag = !showFlag; } }) //點擊選擇條數 // $('.pageSelectShow li').click(function (e) { console.log(e.target.innerHTML) var countLength = e.target.innerHTML for(var i = 0; i < countLength.length;i++){ console.log(countLength[i]) } $('.numSelect').text($(this).data('num')); allCount = Math.ceil(dataLength / e.target.dataset.num); if(allCount == 1){ firstDis(true, 'not-allowed', '0.5'); lastDis(true, 'not-allowed', '0.5') }else{ firstDis(true, 'not-allowed', '0.5') lastDis(false, 'pointer', '1') } $(this).addClass('nowtouch').siblings().removeClass('nowtouch') $('.pageSelectShow').css({ 'display': 'none' }) $('.icona').css({ 'background-image': 'url(' + './down.png' + ')' }) }) //點擊首頁 $('.firstPage').click(function () { numcount = 1; $('.showPage').text(numcount); firstDis(true, 'not-allowed', '0.5') lastDis(false, 'pointer', '1') }) //點擊上一頁 $('.prevPage').click(function () { var prevNum = Number($('.showPage').text()); prevNum--; $('.showPage').text(prevNum); if (prevNum == numcount) { firstDis(true, 'not-allowed', '0.5') } else { lastDis(false, 'pointer', '1') } }) //點擊下一頁 $('.nextPage').click(function () { var prevNum = Number($('.showPage').text()); prevNum++ firstDis(false, 'pointer', '1') $('.showPage').text(prevNum); if (prevNum == allCount) { lastDis(true, 'not-allowed', '0.5') } else { lastDis(false, 'pointer', '1') } }) //點擊尾頁 $('.lastPage').click(function () { numcount = allCount $('.showPage').text(allCount); firstDis(false, 'pointer', '1') lastDis(true, 'not-allowed', '0.5') }) //當頁碼為1,禁止點擊的函數 function firstDis(boolVal, cursorVal, opacityVal) { $('.firstPage').attr('disabled', boolVal); $('.firstPage').css({ 'cursor': cursorVal, 'opacity': opacityVal }) $('.prevPage').attr('disabled', boolVal); $('.prevPage').css({ 'cursor': cursorVal, 'opacity': opacityVal }) } //當頁碼為20,禁止點擊的函數 function lastDis(boolVal, cursorVal, opacityVal) { $('.lastPage').attr('disabled', boolVal); $('.lastPage').css({ 'cursor': cursorVal, 'opacity': opacityVal }) $('.nextPage').attr('disabled', boolVal); $('.nextPage').css({ 'cursor': cursorVal, 'opacity': opacityVal }) } //鍵盤事件 $('#goPageInp').on('keydown', function (e) { if (e.keyCode == 13) { var vals = e.target.value; console.log(Number(vals)); $(this).blur(); if(Number(vals) && Number(vals) <=allCount ){ $('.showPage').text(vals); if (vals == allCount) { firstDis(false, 'pointer', '1') lastDis(true, 'not-allowed', '0.5') } if (vals == numcount) { lastDis(false, 'pointer', '1') firstDis(true, 'not-allowed', '0.5') } e.target.value = '' }else{ alert('輸入錯誤'); e.target.value = '' } } })
以上就是使用javascript實現前端分頁效果的方法的簡略介紹,當然詳細使用上面的不同還得要大家自己使用過才領會。如果想了解更多,歡迎關注億速云行業資訊頻道哦!
